You should see them try to figure out the decimal equivalent of 2/3’s.
I saw some kids trying to solve that one for math class once.
I was just horrible at math in school and I survived it enough to get a passing grade. It wasn’t till I was in My 40’s and I was in the Water Treatment biz that I actually had a really good reason to use it. Up until then I had only used the basics making change in the Retail biz.
When I got to Water Treatment then all the other stuff was something I could actually use. I honed My math skills in making Spreadsheets to simplify calculation for Chemical Dosing, water consumption, Tank sizes, Flow and Capacity of Pipelines by creating the Formulas in the Spreadsheet so I could calculate what I needed to know in seconds by entering a couple of values and getting the correct answer. The old way was to use a calculator for each item and having to do it twice to double check the input on the calculator keys.
The calculator was a PIA !!!
